New "Exit Normal" and "Exit Secret" cheat codes
Adds a couple of new cheat codes (and keybinds):
idexitn -- exits the map normally, as if an exit linedef was used
idexits -- exits the map to the secret level, as if a secret exit linedef was used
These two are super-useful for testing out (U)MAPINFO work and verifying that intermissions work as intended, since IDCLEV and company skip the intermission entirely.
Sorry to bother y'all with this, but before merging, would someone be able to double-check that the options appear in the menu correctly? I had this all tested and working, but needed to merge latest master to resolve a minor conflict and cmake no longer works for me, so I'm unable to test this out post-merge until all that gets resolved. 9_6
@XaserAcheron were you ever able to get cmake working?
Sorry, I ended up getting mired in Real Life(tm) shenanigans -- it may be a while before I can get back to this one.
The fact there's bindable console commands makes this technically doable without this PR, though, so it's not really that essential. :P
We can follow up on discord or open a separate issue about that in the future in that case, I'll close this one.
